Truth bender (4)
I believe the answer is:
liar
'truth bender' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for liar that I've seen before include "Person telling stories" , "Perjurer" , "One not telling the truth" , "Person regularly 'economical with the truth'" , "Dishonest person" .)
